Highly oscillatory unimodular Fourier multipliers on modulation spaces

Fabio Nicola, Eva Primo, Anita Tabacco

We study the continuity on the modulation spaces $M^{p,q}$ of Fourier multipliers with symbols of the type $e^{i\mu (\xi )}$, for some real-valued function $\mu (\xi )$. A number of results ar…
